Check valve (1)
Overview
Features
Hydraulic symbols
This check valve is used for allowing the flow
from one direction to pass freely according to
the cracking pressure of the valve and for
blocking the flow from the opposite direction.
1. There are an in-line type that has thread
connection system and a right angle type that
has gasket connection system.
2. There are six types of cracking pressure with
no spring: 0.01, 0.05, 0.15, 0.29 and 0.39 MPa.
3. Cartridge type elements are also
manufactured.
